Updated url for get started link on start page
Remove outer describe from test

We aren't going to need the extra nesting for the new version of this
page.
Stub new test for new page. Removed old tests.

The flow is completely different in the new design so abandoning all the
existing tests for this page and starting again.
New route for /search

Test no longer pending, so this now executes the setup block which
expects this route.
The start page is staying, so when the user clicks through they will
end up at this search url where they can find the schemes.
